Yesterday I notice a little red dot on his tail, today I noticed one more red dot.

He is still swimming VERY active

There are so many different recommendation online but I am not sure which to trust

I HAVE USED

- Bettafix (which petsmart recommend) at first it worked an than about 2 weeks later the fin rot came back but much worse.

I used a 1/2 tsp mixed in his 1 gallon tank everyday for 6 days and on the 6th day I did a full water change (followed directions on bettafix bottle)

MY SETUP

1 gallon tank with heater. I have a 55 gallon tank that Mr. Kevin fish will go in when I move in 17 days.

water temp: 78
Food: Top Fin Freeze dried bloodworms
Two fake plants
Glass beads on bottom
1/2 tsp Aquarium salt use each full water change with Top Fin Betta water conditioner (1/2 cap full)

I must be doing something wrong with his care! PLEASE HELP!!!!

How often should I completely change my 1 gallon tank?
Am I using the right amount of aquarium salt?
Should I be doing more partial water changes and less full water changes?
How can I get rid of the fin rot for good?
What is this new thing I noticed on him (red spots)?
